실험 절차
To an ice cooled solution of tert-butyl 3-((4-fluoro-2-methylphenyl)amino)azetidine-1-carboxylate (D30) (300 mg, 1.07 mmol) in dichloromethane (2 ml), a mixture of trifluoroacetic acid/dichloromethane (4.5 ml/1.5 ml) was added and the mixture stirred at room temperature for 1 h. Solvents were evaporated in vacuo and the resulting residue was purified by SPE-SCX cartridge (10 g). Collected ammonia fractions, after solvent evaporation afforded the title compound (D55) (0022/107/1) (190 mg)
